Ingredients needed 🛒1 servings
- 150g smoked duck
- 1 tbsp minced garlic
- onion (a suitable amount)
- cabbage (a suitable amount)
- 2 tbsp tonkatsu sauce (or steak sauce)
- 1 serving udon noodles
- 1 cup water
- mung bean sprouts (generous amount)
- salt (a pinch)
- pepper (a pinch)
- parsley powder (a pinch)
- mayonnaise (to taste)
Recipe 🍳
- Place 150g of smoked duck in a heated pan without any oil.
- Cook over low heat until the surface turns golden brown and the duck fat renders out.
- Once the duck is golden, add 1 tbsp minced garlic and lightly stir-fry to infuse the garlic aroma into the nutty duck oil.
- Thinly slice leftover onion, cabbage, and other vegetables from the fridge, add generously, and stir-fry together.
- Add 2 tbsp of tonkatsu sauce (or steak sauce) over the vegetables and gently stir-fry until the sauce blends well.
- Pour in 1 cup of water so the pan is slightly wet, then add the 1 serving of udon noodles.
- Cover with a lid to steam and soften the noodles; once tender, gently separate them with chopsticks.
- When the noodles are fully loosened, add a generous amount of mung bean sprouts and quickly stir-fry just until wilted to retain a crunchy texture, then season with salt and pepper.
- Transfer to a plate, sprinkle with parsley powder, and drizzle mayonnaise in a zigzag pattern to add richness according to taste.
- In a dry pan, cook smoked duck over low heat until golden and the fat renders out.
- Add minced garlic and vegetables, stir-fry with tonkatsu sauce, then add 1 cup water and udon noodles.
- Cover to steam the noodles until tender, gently loosen them, add mung bean sprouts, quickly stir-fry, and finish with mayonnaise.
Cooking tips 💡
- If you don't have tonkatsu sauce or steak sauce, you can substitute by mixing 1 tbsp regular soy sauce, 1 tbsp oyster sauce, and 1/2 tbsp sugar.
- If you try to separate frozen or hardened udon noodles by force, they will break. You must add water, cover with a lid, and steam them until they become soft.
